This has worked great until the last Plex update. I updated within the Plex app itself on MX, and now when I launch it I get "No Connection". It has been launching with Firefox, so I tried making Chrome the default browser and no luck with that either. I also tried booting into systemd kernel, but it made no difference, still shows no connection and the Plex server is not showing up when I look on my Roku either. I do have a working Internet connection on the MX 18 server.
Appreciate any help with getting this working again. Thanks.

EDIT: Though I'm marking this solved I really have no idea what fixed it. I completely removed Plex using Synaptic, then tried to reinstall using MX Package Manager. During the install it stopped toward the end saying their was no default plexmediaserver file. I rebooted anyway and everything seems to be working now, Plex launches and shows up on my Roku. I'm also booting into the systemd kernel.
